Detailed Product Description

Nisin is considered effective at controlling a wide range of gram-positive organisms including: Listeria, enterococcus, Bacillus sporothermodurans, and clostridium. Used alone, it is not effective on gram-negative bacteria (like E coli ), yeasts, and molds. However, research suggests that it may be useful against some gram-negative bacteria when used in conjunction with other preservatives.

In conclusion-based on the way it is manufactured, its GRAS status, and its "natural" labeling designation-nisin appears to qualify as a safe and natural food preservative.
